Lu Xiu Jing (406-477) was a Taoist priest of the Southern Song Dynasty. His courtesy name was Yuande. He was from Dongqian (now Dongqian, Zhejiang). He was a descendant of Lu Kai, the famous prime minister of the Eastern Wu during the Three Kingdoms period. He studied Confucianism since he was young and was also interested in the I Ching, the Hexagram, and the Oracular Inscriptions of the River Luo. After he became famous, he especially liked the Taoist way of cultivating health and quietness, so he left home to live in seclusion on Yunmeng Mountain. Later, he traveled to famous mountains all over the world, searching for traces of immortals and collecting Taoist books. His footsteps once reached as far as the Jiuyi and Luofu mountains in the south and the Qingcheng and Emei mountains in Ba and Shu in the west. In the 30th year of Yuanjia (453), he came to Jiankang (now Nanjing, Jiangsu) to sell medicine. Emperor Wen of the Song Dynasty ordered Zuobu Zhi Xu Zhan to invite him to the palace to preach. Later, he avoided the Taichu Incident and left the capital for a tour of the south. In the fifth year of the Da Ming reign (461), he established a Taoist temple in the southeast of Mount Lu and lived there in seclusion. In the third year of the Taishi reign (467), he was summoned to Jiankang again and lived in the Chongxu Pavilion on Tianyin Mountain in the northern suburbs. During this period, he collated and arranged the large amount of Taoist scriptures he had collected over a long period of time, distinguishing between authentic and fake, and compiled a total of 1,128 volumes of scriptures, including those on precepts, medicine, and talismans, which were divided into three categories (Taoist scriptures of the Three Realms, the Three Realms of the Taoist Scriptures). In the seventh year of Taishi (471), he compiled the “Catalog of the Three Realms of the Taoist Scriptures,” which was the earliest general catalog of Taoist scriptures in Taoist history. Later, the name “Three Realms” in the “Taoist Canon” probably came from this. Lu Xiu Jing advocated that Taoism should be practiced through three methods: worship, chanting, and contemplation of the divine. He compiled more than 100 volumes of Taoist scriptures on the subject of fasting and abstinence, which initially unified and completed Taoist rituals. The Tianshi Taoism he reformed was later called the Southern Tianshi Taoism. He died in Jiankang in the fifth year of Yuanhui (477), and his disciples buried him on Mount Lu, where he was given the posthumous name “Mr. Jianji” and his former residence on Mount Lu was called “Jianji Temple.” During the reign of Emperor Huizong of the Northern Song Dynasty, he was given the title “True Man of the Dan Yuan.”

陆修静 (406—477)南朝刘宋道士。字元德。吴兴东迁(今浙江吴兴东)人。三国时东吴名丞相陆凯的后裔。自少修习儒学，对大易象数、河洛图谶等也感兴趣。成名后，尤好清静养生之道术，于是离家到云梦山隐居修道。后来遍游天下名山，寻访仙踪，广搜道书，其足迹曾南至九嶷、罗浮诸山，西至巴蜀的青城、峨嵋诸山。元嘉三十年(453)，他来到建康(今江苏南京)卖药，宋文帝命左仆射徐湛之请他入宫讲道。后避太初之难，离京南游，大明五年(461)在庐山东南建立道观，隐居修道。宋明帝泰始三年(467)，他应诏再赴建康，住在北郊天印山崇虚馆。在此期间，他将长期收集到的大量道经加以校刊整理，辨别真伪，经戒、方药、符图等书共有一千一百二十八卷，分为三洞(洞真、洞玄、洞神三大类)。泰始七年(471)编定《三洞经书目录》，是道教史上最早道经总目。后来《道藏》中“三洞”的名称，大概就是由此而来。陆修静主张修道应当用礼拜、诵经、思神三种方法，以洗心洁行，达于至道，因此他编撰了斋戒仪范类道经百余卷，使道教仪礼初步统一和完备。经他改造后的天师道，后世称为南天师道。元徽五年(477)卒于建康，其弟子奉葬于庐山，谧为“简寂先生”，他以前在庐山的旧居称为“简寂观”。北宋徽宗时，封为“丹元真人”。
